Christian Serratos laughs and waves towards the cameras following her as she shops around her local Target store in Burbank, Calif., on Sunday afternoon (September 20).

The 18-year-old Twilight starlet had a busy day of errands ahead of her. Before stopping at Target and The Great Indoors, Christian stopped off at a pet store with her pup Gigi. Afterwards, she and a gal pal grabbed lunch at Olive Garden.

Christian has been a busy bee all this week — she lunched with mom Alicia at Lala’s Argentinian Grill before heading over to CityWalk at Universal Studios and also took her boyfriend Halloween shopping.
